COMBINED FE'RRULE AND GUDGEON FOR WOODEN ROLLERS.

SPECIFICATION forming part of Letters Patent No. 255,183, dated March 21, 1882. Application filed December 27, 1881 (No model.)

To all whom it may concern Be it known that I, JOHN LLOYD OWENS, a citizen of the United States, and a residentof Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Combined Ferrule and Gudgeon for Wooden Rollers, of which the following is a specification.

This invention relates to attachments upon the ends of wooden rolls or drums to prevent their being split by thejournals or gudgeons; and it consists in a central hub through which the rod or shaft forming the journal or gridgeon is driven into the Wood or formed in one I end of a drum or roller.

piece therewith, and provided with branching arms or webs having-T heads adapted to inclasp a portion of the circumference of the drum, as hereinafter set forth. I attain these objects by the use of the mechanism illustrated in the accompanying drawings, in which- Figure l is an outside view of the side of one Fig. 2 is a sectional view, and Fig. 3 is an end view, of the same, showing the manner of constructing the ferrule when the gudgeon is formed separately; and Fig. 4 is a sectional view, showing the construction when the ferrule and gudgeon are cast in one piece. Fig. 5 is a perspective view of one end of a drum or roller, showing the manner of Forming it for the reception of the ferrule. Fig. 6 is aperspective view of one of the ferrules detached.

Ais the wooden roller or drum,having a hole bored in its end for the reception of the gudgeon B, and with grooves orchannelsabranching from the central hole to the circumference of the drum, as shown in Fig. 5. The upper portion of the hole for the gudgeon B is enlarged to receive a collar, 0, which fits closely around the gudgeon, and is provided with a number of arms or webs, 11, corresponding to the channels a branching outward from it, as shown. Across the ends of the arms b are T- heads 0, with their lower edgesd, and thicker upper edges, 6, thus making the T-heads wed geshaped. The central collar, 0, and arms I) will also be slightly wedge-shaped and somewhat larger than the channels a and the hole for the collar, so that when the ferrule and arms, as shown in Fig. 6, are driven into the end of the drum the collar and arms will fit the wood tightly, while the wed ge-shaped T-heads a will compress the wood beneath them from the outside and firmly clamp the drum, and hold the ferrule in place and support the wood and prevent its being split. The T-heads 0 will conform on the outside to the surface of the drum, so that no projections occur when the ferrule is in place. By this means a large amount of the surface of the wood is in contact with the metal, so that the holding power of the ferrule is greatlyincreased, while the whole strain outward is upon the collar 0 and not upon the drum. The gudgeon may be formed separately, or in one piece with the central collar and T-arms, as shown in Fig. 4., and the gudg'eon may he made hollow, as in Fig. 4, or solid, as in Figs. 1, 2, and 3.

The invention is especially applicable to the elevator drums or rollers ot' grain-harvesters.

What I claim as new is The central collar, O, arms I), T-heads 0,-and gudgeon B, separately or in one piece therewith, in combination with a wooden roller, A, substantially as and for the purpose set forth.

In testimony whereof Ihave hereunto set my hand in the presence of two subscribing witnesses.
